It makes me sad that this needs to be done here :(

How hard would it be to move all of the android stuff into AudioManagerAndroid?

One way would be for ReleaseOutputStream() and ReleaseInputStream() to return a
bool of true or false if there are any streams left.

Then AudioManagerAndroid just needs to override these methods and check the
return values to handle the android specific bits.  Doing this allows you to
keep all the android stuff in Android.
